Hey,
have anyone tried the GCNN instance selection method of the ISPR package?
I think it is not working. I always get the same error: "The setup does not seem to contain any obvious errors, but you should check the log messages" --> java.lang.NullpointerException

Yes, you are right, there is a bug in this operator. I’m the author of this extension, and soon I’ll provide an update or even a new version of this extension with many new features ex.
- New instance selection algorithms
- Ensemble of instance selection
- More recent version of LVQ algorithm etc.
The new version requires some clean-up to make it publically available. Around the end of September it should appear on the marketplace.
If you are interested I can provide you with the development version where both the GCNN and GENN work good.

ahh alright. Thank you for the information and thank you for the extension. It is an awesome ex. At the moment, I don't need GCNN and GENN. But I am impatient to see the new version ;-)
